The Cisco Catalyst 4224 Access Gateway switch extends data, voice, and
video to the small branch office that deploys IP Telephony in an unprecedented
fashion. With the delivery of IP routing, Ethernet switching, and voice gateway
capabilities into a two-rack unit (2U) chassis, the deployment of converged IP
communications has never been easier or more cost effective. For more
information about the Catalyst 4224 Access Gateway switch, refer to these
The Catalyst 4224 has twenty-four 10/100 switched Ethernet ports with
integrated inline power, and advanced Quality of Service (QoS) features. This
makes it an ideal choice to extend Cisco IP Telephony-based Voice over IP
(VoIP) networks to small branch offices of up to twenty-four users.
The Catalyst 4224 includes an integrated eight-port Foreign Exchange
Station (FXS) module to support devices such as analog phones, fax machines,
and modems. The Catalyst 4224 shares a modular Voice Interface Card (VIC), and
WAN Interface Card (WIC) with the Cisco 1600, 1700, 2600, and 3600 series
platforms. This protects customer investment, streamlines operation costs
associated with sparing of parts, and simplifies training.
